The inlet-pipe 5is connected to be perpendicularly adjusted to suit the detheperpendicular pipe 7, said pipe 7 being threaded on its interior surfaceand passing through the top of the receptacle 1, the threaded collar 8and the threaded washer 9 surrounding the pipe 7 at the point where thesaid pipe enters the receptacle 1, said collar and washer being arrangedas shown in Fig. 2, and effectually prevent the escapement of any gas atthe point where the pipe 7 enters the receptacle 1. The top 10 of thedeflector and pressure-regulator is journaled to the lower end of thepipe 7, as shown in Fig. 2. The stationary sides 11 11 are located atopposite ends of the top 10. The said sides extend down perpendicularlyand are serrated at their lower edges. The said sides 11 extend forsomedistance beyond the lateral edges of the plate of the top 10, as shownin Fig. 5. The flaps 12 12 are hinged to the longitudinal edges of thetop 1. The ends of the flaps 12 12 come in close proximity to theextended ends of the sidesll, the said sides thus closing the ends ofthe flaps 12. The flaps 12 12 are also serrated at their lower edges,and the said flaps may be provided with the pockets 13, adapted to carrysuitable weights. The perpendicular rods 14; 14 extend from the top tothe bottom of the receptacle 1, said rods passing through suitableperforations in the top 10 of the deflector. Said rods prevent thedeflector and pressureregulator from revolving Within the receptacle 1.Y

The perpendicular position of the deflector and pressure-regulator maybe varied by disconnecting the pipe 5 from the pipe 7 and by revolvingthe' pipe 7 within the collar and washer 9. Thus the deflector at thelower end of the pipe 7 will be elevated or depressed, as the case maybe, in a perpendicular line.

The normal position of the deflector and pressure-regulator at the lowerend of the pipe 7 is about that as shown in Fig. 2that is, the loweredges of the sides of the flaps3 are submerged beneath the surface ofthe oil in the receptacle 1, and thus as the gas is introduced from thepipe 7 beneath the said deflector the said gas is forced beneath thesurface of the oil, and by means of the serrated edges of the sides 12and the flaps 13 the said gas is thus broken up in fine particles andpassed through the oil. Thus the entire molecular expenditure of the gasis brought in direct contact with the oil and all uncarbonized elementsin the gas are thoroughly carbureted, and if the pressure of the gas inthe supplypipe 5 be abnormal the flaps 13 13 willswing out, as indicatedby the dotted lines in Fig. 4-, and thus the gas within the enricher andwithin the service-pipes of the house can be maintained at a desiredpressure. The swinging' of the flaps 12 12 may be limited by p1acingshot or bars of lead or other heavy objects in the pockets 13.

The service-pipe 6 is connected to the upper end of the pipe 15, saidpipe 15 being threaded on its exterior surface. The said pipe 15,passing through a collar and washer,

- of the diaphragm 31.

is made similar to the collar 3 and washer 9 of the pipe 7. Thelenticular bulb 16 is fixed to the lower end of the pipe 15. Said bulb16 is opened at its lower end, and the bulb maintains the perpendicularposition within the receptacle 1. The interior of the bulb 16 is dividedby the horizontal perforated partitions 17 17 into a number ofhorizontal compartments. Said compartments are alternately filled with achemical 18 and sponge 19. The perpendicular position of the bulb 16 maybe Varied by disconnecting the pipe -6 from the pipe 15 and manipulatingthe pipe 15 in a manner similar to that described for pipe 7.

The enriched gas in passing from the receptacle 1 passes through thecontents of the bulb 16, the chemicals and the sponges removing allimpurities from the gas, the shape of the bulb'bein g such that shouldany condensation of oil take place within the bulb the said oil isconveyed back into the enricher, and thus such condensation is notpermitted to pass into the surface of the pipes of the house.

The top extension 2 is provided with a perforation 20, which is adaptedto receive the valve-casin g 21. Said casing is provided with ahorizontal diaphragm 22, having a perforation 23, forming a valve-seat.The valve 24 is adapted to close against said seat. .The valve-stem 25extends perpendicularly from the valve 24, and the washer 26 is fixed ator near the upper end of the stem 25. The spiral spring 27 is interposedbetween the washer 26 and the upper surface of the diaphragm 22. TheWasher 26 is provided with suitable perforations adapted to permit theoil from the can 3 to pass from the can into the extension 2. The flange28 extends perpendicularly from the casing 21, said can being threadedon its exterior surface. The valve-casing 29 is provided at its upperend with a suitable thread serrated and adapted to engage the externalthread at the lower surface of the collar 30, said collar 30 beingpermanently secured in the oil-outlet of the can 3. The valve-casing 29is provided with the diaphragm 31, said diaphragm having a centralperforation and a valve-seat 32. The valve 33 is adapted to closeagainst the seat The stem 34: extends perpendicularly down from thevalve 33, and the perforated washer 35 is fixed at or near the lower endof the stem 34:. The spiral spring 36 is interposed between the washer35 and the lower surface The outer surface of the extension 37 isbeveled and corresponds with the inner beveled surface of the extension28. The collar 39 is journaled onthe valvecasin g 29. Said collar isinternally threaded and is adapted to engage the thread of the flange28, and thus the valve-casings 29 and 21 are held together, as shown inFig. 7.

When the can 3 is connected to the extension 2, the ends of thevalve-stems 34 and 25 come in contact with each other, and the flaps areopened, as indicated in Fig. 7. Then the can 3 is disconnected from theextension 2, the coiled springs 27 and 36 cause the flaps 2i and 33 toclose. Thus the outlet-can 3 and the inlet to the extension are bothautomatically closed when the can is disconnected from the saidextension. The vent 40 is connected to the upper end of the can 3. Saidvent passes perpendicularly along the side of the can 3, and the saidvent is connected by suitable valves at 41 with the interior of theextension 2. The construction of the valves at 41 is substantiallysimilar to that of the flaps within the casing 21 and 29, with theexception that the flaps at 41 are made on a much smaller scale. Theflaps at 41 are adapted to open automatically when the vent 40 isconnected to the extension 2, and the said flaps are adapted to closeautomatically when the said vent 4.0 is disconnected from the extension2.

lVhen the receptacle 1 is empty and the filled can is connected to theextension 2, the oil passes from the can 3 into the extension 2 and intothe receptacle 1. At the same time the gas passes up the vent 40 andenters the can above the surface of the oil therein, and thus the samepressure is maintained within the can 3 that is within the receptacle 1,and there is no interference with the free passage of the oil from thecan 3 into the enricher. Then the surface of the oil within the enrichercomes in contact with the top 42 of the extension 2, the passage of thegas through the vent 40 is cut off, and thus as there is no elementpermitted to pass within the can 3, above the surface of the oilcontained therein, the said oil immediately stops flowing into thereceptacle 1, and thus the oil in the receptacle 1 cannot assume agreater depth than about that shown in Fig. 2. As the oil in thereceptacle 1 is evaporated or absorbed by the gas passing therethrough abubble of gas is permitted to pass through the vent 40, and thus moreoil is let into the receptacle 1 from the can 3, and thus the enricheris provided with an automatic oil-feed adapted to maintain the oilwithin the enricher at a certain predetermined depth. The top 42 of theextension 2 is supported, as shown in Fig. 2, by the reinforcing-strips43, which connect the top and the bottom of the extension 2 and preventthe weight of the can 3 and its contents from concavin g the said top42.
